To all whom t may concern.'

Be it known that we,v CHARLES D. MODON- ALD and CHARLES E. ENNns, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Placing PaperRings in vCan-Heads, of which the following is a specification.

he present invention relates to a machine for cutting and positioning a liner in fthe form of paper ring within a groove or seat in a can head.

The objects of the invention are to position a circular paper disk within a seat in a carrier to move the carrier into position, where the disk carried thereby will aline with a cutting die .which is operated to cut the center' out of said disk and form a ring; to carry said ring into position to aline with aA seat in a second carrier, in which has been positioned a can head; to operate a positioning die for forcing the ring into the seat in Vthe alined can head; to then spin or turn over the edge of the can head, thereby firmly securing the ring in position; and to then stack the completed can head with the liner therein within a. suitable receptacle. All oi' the above is carried out automatically, whereby the operator has no duty to perform save replenishing from time to time the supply of disks and can heads, and carry away from time to time the can heads with the liners therein. y The invention further consists in the features of construction and combination of parts hereinafter: described and claimed.

In the drawings: Figure 1 is a front view ot' the machine of the present invention; Fig, 2 is an end View of said machine; Fig. 8 i` a plan view; Fig. 4 is a section on line of Fig. 3, looking in the direction of the ari rows; Fig. 5 is a section on line 5 5 ot Fig. 1, looking in the direction of the arrows; Fig. 6 is a section on line 6 6 offFig. 1, looking in the direction of the arrows, with the transmission mechanism only; Fig. 7- is a view of the paper disk; Fig. 8 is a view of the ring liner formed from said disk; Fig. 9 is a section showing the ring liner in place; and Fig. lO iS a section showing the ring liner in position within the can head and the edges of the can head turned over to retain the ring in place.

In the art to which the present invention relates, the feature to be accomplished is the positioning of a ring liner within a can head which acts as a seal when the head is placed upon a can, thus preventing a leakage and consequent spoiling of the contents. In the present invention, this assemblage is brought about by automatic means, the only manual operation being the placing ot' the can heads and paper disks within suitable magazines, and the stacking or piling of the can heads with the liners therein within a suitable rei ceptacle.

The mechanism is mounted upon a frame consisting of a base 11, supporting legs 'or standards 12, and a top or table 13; lThis supporting frame can be of any suitable construction. The machine embodies three n'iagazines or containers; the irst, designated generally by the numeral 14C, being for the paper disks; the second, designated generally by the numeral 15, being for the can heads; vand the third, designated generally by the numeral 1G, being for the purpose of receiving the can heads after the rings have been positioned therein.

The lirst step in the operation of the machine is the extracting of the paper disks from the i'nagazine or receptacle 14e. This magazine, as shown, consists of a tubular member 17 held in position by a suitable bracket or support 1S, the magazine, as shown, having its lower end spaced away from the table 13. In order to prevent more tlian one of the disks whiclr, are designated by the numeral'lg from being extracted at a time, pivoted fingers or "keepers 2() are provided, which underlie tlib lowerniost of the pile of disks within the receptacle. The extraction of tin1 ,disks is brought about by means ot' a si1ctioirl1ead 21 which is attached to a tubular member 22, the interior of which is in communication with a suction supply pipe 23 extending from any suitable source of suction.

The tubular member 22 is attached to a slottedV plate or stiaddler 24- which carries a roller 25, resting against the periphery `the coperation of the spring 28. Each time the suction head engages with the lowermost of the disks 14 within the receptacle 17, it will adhere thereto, and the downward movement of the suction head will extract the disk from the pile within the receptacle and bring it into a 'seat 29 in a revoluble disk or carrier 30. The seats 29 are composed of companion members 30,

each formed of companion semi-cylindrical producing the ring 52rl shown in Fig. 8. The

center portion of thisring drops into a chute 521 fand lsthus discharged, and from 1t a second ring, for use with a smaller sized can head, canV be made.`

The means for moving the 'slidable head up and down consists of a member 53, to each end of which is attached a rodA 54 con- -nected vwith the head 51, and depending from the member 53 is a piece 55 carrying a lroller 56 traveling withinv the groove 57 of a-cam 58`mounted upon -the shaft 27. As

.will be apparent from Fig. 5, as this can revolves, it will force the member 53 up and down, and'through the' instrumentalities of portions 31, to each of which is attached the connection 54 between .the member 53 plate 32. Each oftheseplates is s lidablel within la way 33 and 'is held normally pro- .jected forward by a spring l34,- and each of the lplates has an upwardly extending protuberance or shoulder 35, the lfunction of which will hereinafter appear. The inner dia-meter of the seat 29 is somewhat smaller than the outer diameter of the disk, whereyFairy, when the disk is pulled bythe suction cup downv into theseat,y the hold of the suetioncup will be broken by the disk engaging with the portions 31 of the seat, and the disk will thus be deposited in the seat. After the disk has been thus deposited, the' next operation is a movement of the carrier 30a quarter revolution, and at the same time this carrier is'moved a can head vcarrier 36 is also moved a similar distance. The mechanism for causing this advancement is shown better in Figs. 3, 4, and

6, and comprises Va Geneva wheel 37, oper-7. ated by an arm 38, which is carried by a disk 39. This. disk is rotated by the movementsof a shaft 40, andthe shaft inturn has secured at its lower end a beveled gear 41' meshing with a beveled gear 42 mounted upon the main drive shaft 27. The Geneva wheel isv attached to a stub shaft .45, to

which is secured at one end a gear 46, and to the other. end of which is secured the can top carrier 36. The gear 46 meshes with a pinion 47 which meshes with a gear l48 that is secured to a stub shaft 49, which shaft carries and revolves the disk carrier 30.4

From the foregoing,' itwill be apparent that each of the carriers 3Qand 36 isre volved in a step by step movement,'but in A. oppositey directions, as'indicated bythe arrows in Fig. 3. The first movementof the car- 'rier 30 brings the disk o f paper carriedthereby beneath a ring cutting male die member 50 with whichis associated a spring backed stripper ring 50d. The members 30'1L 0f the seats -29 act as eopera-ting female dies for this male die 50. This die member is'carried by au elongated traveling head 51 which-is and the head 51, said head will be reciprocated. The head always moves in a downwardv direction during the period vofy rest of the' carriers 30 and 36, so that the work is always in position beneath the various mem-- bers carried by the head when the head is moved downward* After this ring 52ar has beencut in the-manner above specified, it'is left within the seat, `and the carrier 30 is advanced a second step. This brings the ofa can head 62which' can head lhasbeen advanced' intoposition'beneath the ring by means ofthe movement of the can head car rier 36. Suitable seats 63 are. formed in said carrier to support said heads. The c onf tinued downward movement of the pos1t1oning die forces the ring into the groove 61, and from that point on, the can head and ring. are carried-by the' same carrier until finally discharged. `The next operationA ofl vthe machineis to bring the lcap with thel ring liner in place therein around to a-po sitionwhere' a mechanism acts to bender `drop out of its carrierand into a groove 61 vcrimp the flange-'of the can" headto turn'A over the same.'4 This takes place at the point indicated bythe numeral 64, as. shown in Fig.""3. When in this position, the `cap is l held between spinning dies, comprising an upper die member 65 and a lower die member 66. The die member 65v is carried b-y the head 51 and revolves within a ball bearing,

Ameans of a stub shaft 474, to whichis joined 'jas' is shown in Fig.- 5. The -lower die mem! a beveled pinion 69 driven by a beveled gear 88 on' a stub shaft 43 connected 'to the main iso" and the head vfalls upon the guide 91, and is directed thereby downwardly and onto the table 92 where the finger 93 engages it, and

mdves it into position beneath the magazine 16. Then the plunger 9S acts to force the completed can head through the fingers 97 and into the interior of the magazine, from whence it is ultimately removed. At the same time that the sucker head 21 acts to eX- tract a disk from the magazine, the plateA head 'with the liner therein in the magazine4 16, the downward movement of the head 51, and subsequent actions of the cutting die 50, the assembling die 59, the spinning dies 65 andI 6G, and the inward movement of the roller T5-#these all take place-at practically the same time. The second movement is the revolving movement 'of the carriers 30 and 3G which is intermittent as respects the op# eration of the other portions of the machine.

Thus, there are two sets of movements, one alternating with the other throughout the operation of' the machine.
